Baum

A collapsible polypropylene bottle made with the same joined-G-code approach as Bruk. The cap folds to seal, and the body can fold into itself like an accordion when empty.

Joined G-codeThree Cura-generated G-codes are manually placed one after another to keep the print path continuous.
QualityAvoiding unnecessary retractions helps reduce stringing and keeps the surface cleaner.
Cleaner pathBruk and Baum use joined Cura sections so the pattern keeps flowing instead of stopping, retracting and leaving small defects.
